Writer has a 2003 sonata. My drivers rear caliper would wear down the brake pads very fast and the others would be like new. After 2 visits the caliper was replaced. After 2 days of sitting in the garage I'd back the car up and hear grinding. The dealer said it was just rust on the rotor and it stopped after driving a few minutes. After being put in storage over the summer to drive my sports car during the summer I went to driver the sonata. While sitting in the warehouse during summer all four rotors rusted up beyond being able to drive the car safely. And the front calipers seized up. The rotors looked like the car had 150,000 miles on it. I have my sports car stored in the same place through winter and the brakes and rotors are fine in spring. The general manager from the dealer says they will check it out and see what can be done. The car only has 50000 mile on it. I've never seen a cars rotors and brakes do this. Neither has the mechanics I first took it to. The mechanic drove it and had to use the emergency brake to stop the car.
My Hyundai 2003 xg 350 had incidents of lurching powerfully forward or backward even though my foot would be pressed hard on the brakes. It happened three times. The third time it did it, I had it in reverse with my foot on the brakes and while my wife was trying to enter the car on the passenger seat side, the car rabbit jumbed backward and cause her injuries that warranted taking her to the emergency room on September 12 2005. I searched the internet and found out that many other owners had the same exact experience and that they all had trouble convincing Hyundai of the problem. If they can't duplicate the behavior then they refuse to fix the porblem. I try to duplicate the behavior and it took me about 15 tries to succeed. Some internet complainers report that they succeeded in convincing the dealership of the problem and had to replace the whole transmission for them. Hyunday should admit the problem and recall cars.
